Ruled surfaces are any surfaces that can be defined entirely by a swept straight line (essentially an infinite number of snapshots of a line as it moves in some fashion). A right conoid is a special ruled surface in that all of the lines that define it perpendicularly intersect the same straight line. If we determine the fixed line to be the Y axis, then this particular shape is created by move a line vertically a distance equal to its height and then back to its starting point, rotating it 360 degrees over that time.

I probably didn't need to give that little ten-second math lesson to introduce this product but a little knowledge never hurt anyone, right? This is my new Skeletal Right Conoid, a version of the classic mathematical shape that is reduced to a wireframe in order to better show off its unique structure. Slightly larger than 1.5" in all directions, it's the perfect size to hold in your hand or to keep on a desk. It's unique surface is wonderful to fiddle and play with.

Spherigear Triangle was proposed by Bram Cohen. The puzzle has three spherigears that are connected in a triangle by three gears. The mechanism is based on the Spider Gear puzzle, also proposed by Bram. A move is made by turning two or three spherigears together.The object is to scramble the puzzle and then to realign all gears again. One variation has only two instead of three connecting gears. Can you deduce why?

Bram's Shuffle is a twisty puzzle invented by Bram Cohen. It has seven pillowed tetrahedrons that slide around inside a pillowed octahedron. The object is to scramble the puzzle and solve it again. All the tetrahedrons have six degrees of freedom, as they can fully change position and orientation. This makes the puzzle hard and confusion to solve. Related puzzles are Bram's Black Hole and Bram's Rocket.

Here's a bunch of little tiny laser guns I had printed for my minifig collection. They are all stylized homages to weapons that were packed with Transformers toys in the 80s (I get a lot of requests for Transformers-related stuff), so they should work great with the new kre-o toys...but your Lego minifigs could just as easily tote them around.

I spent a couple of months rendering all of these, which was kind of a weird experience because I'm a pretty non-violent guy. The only gun I've ever handled in real life is a Sharper Image "Bug Gun" that I use to capture and release spiders so I don't have to kill them.

Yesterday my models arrived. I am very excited and pretty happy with the results. Take a look, i would love to see some feedback here guys!

Pentafold was proposed by Bram Cohen, inspired by the Gear Fold puzzle and several of Bram's earlier gearing ideas. It is a gear train of five seven-teeth gears. As the gear train has an odd number of gears, it is locked and it cannot turn. Moreover, it is locked by a piece in the center. Pentafold can be folded open in five directions. Once folded open, three gears can turn. This enables to scramble the puzzle. The object of the puzzle is to scramble it and then to bring it back into its original state.

"God's number" for this puzzle is five, i.e. it can always be solved in five moves. Bram found a generic easy-to-remember solution that requires at most eight moves.

So I have a Honda Civic Si and a Ford F-150 that I wanted to spruce up a little. So I made some stem caps for them. The F150 with the Ford logo, and the Civic with the Honda logo and the Si logo (not shown) with Si red in the background. Not for sale for obvious reason, but wanted to share my handy work! Hand painted polished WSF.

Skewb Shift was suggested by Bram Cohen. It is a Skewb version of Gear Shift. When the puzzle is in its rest state, all gears can spin together. Skewb Shift can be pulled a bit apart in four directions.In the pulled-apart state, half of the gears can spin independently of the other half. The object of the puzzle is to scramble the gears and then get them reoriented again.

Amorphature is an invention or discovery by Kirill Grebnev. This set of pieces can be assembled into some interesting shape-shifting objects. It moves in a very sensual way. We do not yet know what the puzzle is.

Hi!
we developed a 3d clip adaptable to a lot of supports (cup, glass, mug etc...)
Using it we designed a series of products that are based on icons of design, fashion and social phenomena, small and funny accessories to be used for parties and events.
If you have any requests we will be glad to develop them using our clip!!!

Chain Cube is an old Oskar design, from 7 March 1983. The puzzle is a chain made of two types of links, namely straight and twisted. The object is to fold the puzzle into a cube. The original 1983 prototype was made in wood. The modern version is 3D-printed plastic.

These came in a couple of weeks ago but I just got around to photographing them.

Just my own take on how to identify all the black (or white!) cables sticking out the back of your computer - an occasional frustration of mine when I come to swap one out for that temporary hookup. I'm sure I'm not alone.

Designed to clip to most 3mm USB cables, they will, with a bit of care, attach to slightly thicker cables, but not Ethernet or power cables.

After seeing Bermuda Comet and Bermuda Jumblix, both "core-mods" of Bermuda Minx, I started thinking whether there would be a fourth geometry that can use Bermuda Minx pieces. Then I remembered Rhomdo, and surprise-surprise, also that geometry can be built from these pieces.

I find it quite surprising that pieces of a puzzle can be reused for another puzzle with a completely different geometry. I find it even more surprising that the pieces can be used for four different geometries in total. Or would there be a fifth geometry as well? Do we know any other twisty puzzles that can be "core-modded" into each other?

Bermuda Jumblix is a serendipitous combination of Jumblix and Bermuda Minx. Jumblix was designed by Oskar in 2009. Then in 2012 Bermuda Minx by MF8 came out. Baiqiang from China discovered that parts from that puzzle could be reused to build Jumblix, requiring only a new core. This Shapeways model is that new core. The fit is not perfect, as the angles inside a regular dodecahedron are a few degrees different from a pentagonal prism, but the turning is surprisingly good despite that. I am still wondering how Mr. Baiqiang discovered this.

The pieces of Bermuda Minx and the new core can be used to build the regular Jumblix and many "Bermuda-ized" variations of Jumblix. And those pieces can also be used to build a regular Crazy Comet and many "Bermuda-ized" version of that, see the post on Bermuda Comet.

I find it quite surprising that pieces of a puzzle can be reused for another puzzle with a completely different geometry. I find it even more surprising that the pieces can be used for a third geometry as well. Obviously, this is some sort of modding, but it is definitely not shape-modding. Would "core-modding" be a proper term for what is going on here?

Always eager to avoid the $6.50 shipping, I've gotten another giant lump of toys all at once.

Here are spaceships:
We're looking at 3 Centauroi ships, 3 Goblin ships and 2 Sylvan ones. None of them have official names yet. This completes the 15 core-set space ships for the Rune Star series.

And here's the Dwarf. This is my D&D character, Helja Granitasker, a Dwarf sorceress with the Dragonic Bloodline background, and armor proficiency feats. (NRRRRRRRRRRRRD!!!) She is also the prototype for making an entire line of "infantry" units that will go along with the spaceships. Thus, there are many forms of Helja here so that I can see how they will come out.

Here are the 3 scales available. 1:36, 1:54 and 1:72, which probably sound a bit weird to miniature enthusiasts. 1:36 is for GURPS, where 1 hex = 3 yards. It is made assuming that players are using a grid of 1" hexes. 1:54 should roughly match the scale of D&D or Reaper miniatures. 1:72 is a popular scale, and also works for GURPS players with 1/2" hex grids. The bases are meant to fit into the appropritate GURPS or D&D grids.

Here we've got different ShapeWays materials, WSF, Frosted Detail and Ultra Detail. I really love the Ultra Detail. This one really looks and feels the way I expect from plastic toys. I think the frosted detail might work just as well for larger models once it's painted, but I can't see it so well because it's so... frosted. I don't know what kind of paints to use on the Detail plastic, since my acrylics pile on top of the existing details.

One of the cool things about using 3D models to make this is that I can just rig it to an armature and do it again in as many poses as I want. I also want to try making some more interesting sculptures, like this one of her using her Daily Power (NRRRRRRRRRD), Lightning Breath. I really should have drawn the lightning bolt on paper before modeling it.

Using a 3d scan of actual tree bark in the background of the shield, this talisman has an inset symbol of a Celtic Tree of Life.
Chosen as a symbol of renewal, and both reaching towards the heavens while remaining grounded.

Having the symbol in a shield can have two meanings, either protecting the symbol or having the symbol protect you. I'm fond of the second meaning myself.

I've got plans to come out with a system that will allow for somone to easily customize their own shield talisman, based on a selection of shield shapes, shield finishes, backgrounds, and symbols.

Bermuda Minx is a serendipitous combination of Crazy Comet and Bermuda Minx. Crazy Comet was designed by Oskar in 2009. Then in 2012 Bermuda Minx by MF8 came out. Cube Master Mr. Fok (owner and genius of MF8) discovered that parts from that puzzle could be reused to build a Bermuda Comet, requiring only a new core. The fit is not perfect, as the angles inside a dodecahedron (63.43 deg) are a few degrees different from a rhombic dodecahedron (60 deg), but the turning is surprisingly good despite that.

I designed this HO scale (1/87) trailer for model railroaders because nobody offers a styrene version of this. I'm going to redesign the tank to be one piece. Overall, I was pleased with the finish. The tank had a slightly rough texture like fine sandpaper. But with sanding and priming it should be fine. It didn't have any of the stair-stepping that I was afraid it might have. And the piping on the frame came out better than I expected. The only sour note was the long handrails that run along the top of the tank came out pretty bad. They were just too long and thin. I'll use brass wire instead.
When I get it painted, I'll post some pics.

Note: This is Frosted Detail.

Rob's Pyraminx was suggested at Rob Stegmann's puzzle website. When analyzing all twisty puzzles with a tetrahedral geometry, Rob found an edge-less pyraminx design that has not yet been implemented. Here it is. It has a Skewb mechanism inside, so the puzzle is a shape mod of the Skewb.

This puzzle is arguably the easiest non-trivial twisty puzzle :-). What is it's God's number?

I was cooking in my kitchen one day and noticed how very blank one of the walls was. I've just recently moved in, and I'm still getting the place decorated.
I had been itching to make another Shapeways piece, and it looked like a perfect opportunity to not just put something up on my wall, but MAKE something unique; I wanted something unusual, artistic and a little abstract, yet technical-looking. I also wanted something that INTEGRATED that blank white wall, instead of just sitting in front of it. I hit upon the idea of an Orca - the distinctive black and white constrast colour scheme would make it really visually pop on the wall, giving me a chance to use Black Strong & Flexible which I haven't done before - and the characteristic white patches could be interestingly negative space. And they're beautiful creatures, if nothing else.

I'd also been toying with the idea of the wireframe style models for a while - I think they offer a great final product: an intriguing look, a satisfyingly large object to unbox, and a cheap one too because of the low material usage! It's not really an aesthetic that you see outside 3D printing. This was the perfect time to experiment.

I'm really pleased with how it came out, and it was surprisingly quick to build - the modeling was done in an afternoon. The major issue I came up against was discovering the best orientation for printing - most of my experimental uploads came out costing almost $100. Final cost is about $25 or 18 euros, but satisfyingly big at about 30cm nose to tail.

Just got a new prototype for a possible creator. If you remember the Statement Vase this is a riff of that idea. Having tried it out a bit I think I want to put a lip on the bottom so pens don't slide out. I like the looks but it fails a bit on functionality.

You take an image and it tiles it around the cylinder. The image I used for this is here:
